Description of problem:
I have RH 7.2 on my box.
I have a small LAN with 14 pcs in it. And a NAT connection to ISP.
Internet is working properly.
But I cannot ping and browse ISPs machines, except the one, we are
connected to. I have reported our ISP, but they have no firewall tool
cast us (other clients work fine with no problems)
When I do arp
I see some <incomplete> messages to the ISP machines. What it could be,
I have two NICs:
1) IntelPro 100 (eth0 - to Internet)
2) Realtek 8139 (eth1 - to LAN)
Thanks in advance.

you probably have firewall rules on your linux box. Definitely not a bug,
misconfiguration is the cause.
